He has now told E! Online that Lucas returns to help out Haley (Bethany Joy Galeotti).

"Lucas needs to come back to combat some drama that is going on in Haley's life," he said. "And we kind of get a little bit of an opportunity to see what we really loved in the relationship between Haley and Luke."

Murray continued: "It's just kind of a little throwback and a little visit for our fans and for our wonderful following. It's a solution to a problem."
